I wish we had a better alternative to passwords. Something that's actually good, solid, can't lose or forget. I get the feeling we won't have that until we can start implanting chips in ourselves.
So yeah change the password and delete previous versions is a good first step but everything else has already leaked to who knows where.
That was my point: I use my password manager to store those security questions and answers but if someone got ahold of my password manager account I would be screwed because many sites require the answers to those questions to reset a password.
I need to get into the habit of exporting my password list to plaintext csv and storing it in a safe or safe deposit box but I haven't disciplined myself for that yet.
I am worried about the ability for the 1Password database to be hacked if someone were able to get their hands on that.
This is one among several reasons I don't go in for any "cloud" based syncing of password managers. I use keypass and sync the file with syncthing on LAN only mode.
First off, your passphrase should only be used for the password manager itself. So if you accidentally paste it on twitter, you just change your passphrase.
Secondly, you're way more easily fooled than a password manager. I don't know my passwords (they're generated), so to phish me you have to convince 1password as well. That means e.g the google open redirect bug on HN yesterday can't trick me with a fake password page on a different domain.
Third, it makes your passwords way easier to use on mobile. Most of the managers support whatever biometric integration your phone has nowadays, so rather than trying to type your 24 character alphanumeric symbol crap (or worse, a crappy password because you didn't want to make a good one on mobile) by hand you can just paste it in.
Lastly, it encourages you to actually use separate passwords for all your accounts. And when passwords get leaked, your manager can tell you which sites need new passwords.
In conclusion, password managers improve your internet security and experience immeasurably. Go buy 1password!
